What is GSTR 1 and How to file GSTR 1 and what are the areas we could possibly commit mistakes

Posted by : Siddharth Jalan on | Feb 13,2018

Understanding GSTR 1 will help us understand about GSTR-1 mechanism in a better manner. The concept of filing of GSTR 1 can be understood in the light of compliances under Goods & Service Tax. The GST tax structure is such that it mandates monthly return filing, thus making each month a taxable period for generation and filing of a set of returns, namely GSTR 1, GSTR 2 and GSTR 3. Each one of these is to be filed in order to declare the transactions made in the said taxable period by the registered taxpayer to the Government. Among these three, GSTR 1 forms the base document that lists the transaction of supply of goods by the business or trader. In easier words, it is the detailed return prepared for the invoices raised by the businesses towards the buyers.

The right way of learning about GSTR-1 lies with learning about the impact that it makes on GSTR 2 Return filing. As mentioned previously, GSTR 1 becomes the base document on the basis of which the rest of the returns are auto-populated. The mechanism is such that the supplier of goods or services enters the details of invoices raised by him towards the buyer of goods or services, an intimation of the same is sent to the buyer confirming the same in the form of GSTR 2A. After the said transaction is confirmed at the buyer’s end, the details of which get auto-populated in the GSTR 2 at the suppliers end. Or else, in case of discrepancy, this detail gets filed under GSTR 1A at the supplier’s end for further modification or rectification.
